/* Javascript tabs. General usage:
*
* <ul id="jt_select">
* <li><a href="#<name>" id="jt_sel_<name>">..</a></li>
* ..
* </ul>
*
* Can then be used to show/hide the following box:
*
* <div id="jt_box_<name>"> .. </div>
*
* The name of the active box will be set to and (at page load) read from
* location.hash. The parent node of the active link will get the 'tabselected'
* class. A link with the special name "all" will display all boxes associated
* with jt_select links.
*
* Only one jt_select list-of-tabs can be used on a single page.
